HYDROCARBON-BURNER.

Application nled October 9, 1916. Serial No. 124,834.

To all 'whom it may concern.'

Be it known that I, CHARLES A. HAMMi-n., a citizen of the United Statesof America, residing at Los Angeles, in the county of Los Angeles, Stateof California, have invented' new and useful Improvements inHydrocarbon-Burners, of which the followin is a specification. y

is invention relates to that class of hydrocarbon burners in which oilis moved through a burner head by means of steam or air under premureand commingled therewith, and pertains es ecially to improvements in myinvention ydrocarbon burners disclosed in United States Letters Patent748,862, January 5th, 1904.

The objects of my invention are to improve the construction, whereby theburner may be quickly reassembled, after having been taken apart for anypurpose; and to provide a construction whereby the-dura ilit 4oftheburner is increased.

' I ave found that in reassembling burners of the ty e.disclosed in theLetters Patent above refldrred to, the mechanics often fail to exactlyaline the several parts, thereby causing incorrect distribution of theoil in the mixing; chamber, with a consequent unbalancing of the llame.Due to the small di' mensions of some of the steam passages -lead-` ingfrom the e ualizing chamber to the mixchamber, ight displacement willcause umlalancing. `To the endthat correctalinement in asombling may besecured, I have provided means for insuring correct pos1' tion of theparte, with respect to each other.

I have also provided means' for straining the steam to preventimpurities from pass straining the steam and separating therefromforeign matter and the water of condensation.

I accomplish these objects by means of the embodiment of my invention,illustrated 1n the accompanying drawings, in which:

2 is a central, vertical longitudinal section of the burner head.

Fig. 3 is a view looking upwardly of the upper part of the head.

1g. 4 is a plan view of the base of the head.

Fig. 5 is a front view of the upper rear portion of the head. 0Referring more particularly-to the drawing, the burner head is comprisedof a base 6 upon which is mounted a rear part 7 and a tip part 8.

Base 6 is provided with a lon 'tudinally extendin steam inlet bore 9 treaded at the end or receiving a steam pipe. A port 10 communicates withsaid bore and opens through the top of said base. The forward end o thebore is reduced in' diameter and a condensation ort 11 communicates withthe upper part o the base at the forward end. A recess is formed in thetop face ofthe base for the reception of a. wear plate 12. Below thewear plate a. recess 13 is countersunk. the latter flaring laterallyfrom the 'condensationthport 11 and being of relatively small The upperrear part 7 of the head has an equalizing chamber 14 foi-med in thelower face. T he chamber is formed with an inclined wall 16' at theforward end,'thereby forming extensionsy 15 and 17. Leading fromthe'equalizii'i chamber are threeducts e outerV ducts .15 and 17communicate with the extensions 15' and 17', converge and are high andnarrowg' they disehar steam-on lines which will intersect each ot er in'the mixing chamber and thereby thoroughly mix and commingle steam andoil. A cylindrical strainer 18 of perforate material is placed inequalzing chamber 14` above port 10. Above the equalizing chamber andextending 'longitudinally of the head orton 7, is a'n oil supply inlet19 .suitably threaded at the end to receive an oil supply pipe. An oilduct 20 of 'reduced diameter communicates with inlet 19 'and is4directed downwardly toward the lower Fface to a point above steam duct16 and between ducts 15 and 17. Fixed to the head o ion 7 is a dowel pin21, which projects i tly from the front face and is inclined thereto.

The tip part 8 is provided with amixing chamber 22 which flares outwardlj' Its smaller dimension is equal to the istance between the outenwallof ducts 15 and 17. When in position, the rear of chamber 22 shouldexactly register with ducts l5 and il', so that the side walls exactlyrregister with the steam ducts. A Haring passage is therelfy formed inwhich the steam and oil is mixed, and in which there are no projectionsor recesses to unbalance the distribution of steam and oil in thechamber. Such construction I have found necessary for an cllicientworking of the head. Channels are formed at the upper portion of theequalizing chamber for the reception of wear plate 23. A recess isformed on the rear base of the tip 8 to receive the projecting dowel pin2l. To hold wear plate 23 in position, a set-screw 2l is provided.

fr T he head is Iassembled by mounting head part 7 upon base 6 andsecuring it thereto by means of bolts 25. Wear plate 12 is then placedin position, and tip 8 placed on basf` G. Bolts 26 are then tightened upsecuring tip 8 to the base. As the bolts 26 are tightened the tip isalined with respect to the base, so that the side Walls of themixingchamber and ducts 15 and 17 exactly regster.- This is a veryimportant feature of my invention. I have found that unsatisfactory `andinefficient operation of the old type of burner without the dowel pin,after having been taken apart for repairing or cleaning, was due to afailure of the mechanic to properly align the tip 8 and rear portion 7in reassembling the burner. A displacement of one sixty-fourth of aninch from true alinement will materially decrease the efficiency of theburner and result in unsatisfactory operation. With my improvement, itis impossible for the burner to be reassembled without perfect alinementof the steam ducts and mixing chamber.

Water of condensation enters port 9 with the steam and collects in thewell formed below port 10, and is forced forwardly through thecondensation port 11, spread in recess 13, and discharged out at theforward end of the head below the ame. Any boiler scale, dirt or foreignmatter in the steam is caught by strainer 18, and is prevented frompassing out through the mixing chamber. In this way the life of wearplates 12 and 23 is increased, and the 1liability of clogging decreased.These factors allmaterially add to the eliciency and satisfactoryoperation of the burner head. On disassembling the burner for cleaningand renewal, perfect alinement in reassembling is assured and therefore.ellirfent and satisfactory opera- 'liat l claim is: l.
